Systems and Methods for Selecting a White Point for Image Displays

1. A method for converting input image data specified with respect to a first white point of a display panel to a second white point, the steps of said method comprising: solving for weighting coefficients that relate a set of first white point coefficients to said second white point; computing a mapping of a first set of color values utilizing said first white point, into a second set of color values; said first set of color values being derivable from said weighting coefficients: and converting said input image data into output image data using said mapping.

2. The method of claim 1 wherein said first white point is an assumed white point of said display panel.

3. The method of claim 1 wherein said first white point is a measured tri-stimulus white point of said display panel.

4. The method of claim 1 wherein said second white point is a desired white point of said display panel.

5. The method of claim 1 wherein said display panel substantially comprises a subpixel repeating group comprising subpixels in at least four primary colors including white subpixels; and wherein said second white point is the white point produced on said display panel when only said white subpixels are turned on.

6. The method of claim 1 comprising the step of dynamically changing the weighting coefficients of said mapping according to a user preference for said second white point.
